Specification of Letters Patent Application filed August 19, 1918. Serial No. 250,513. s

To all whom t may concern; y

Be it known that I, HERMAN MosoHiiL, a

citizen ofthe United States, and aresidentV of Ottumwa, in the county ofWapello and State of Iowa, have invented certain newv `and useful Improvements Vin VExtensible Hay-Smokers, of'whieh the following is aV specification, referenoebeing hadfto the aocompanying drawings.'

My invention relates p'osite'd upon a head carried "byv 'ai Y"swinging framefand is carried up over thestackerand discharged upon a stack located back of it by the swinging of such' frame; It has par'- ticularly Vto do with staekers of this descrip tion in whielipiovisioii is made for varying the height at which the hay`is discharged from the stacker byV mounting the stacker 1 headupon an eXtensible frame which is carried4 by av swinging lifting frame connectedV l s ranged'to `be operatedV by, draft animals;

with the hoistingmechanism. l

Oneof the objects of my inventioii isto' so arrange the'parts and correlate their action that'the draft required to operate the stacker is lightened'; Another object is to provide improved lever mechanism for hoist-V ingand lowering the stacker head and advancinglor retractingthe same, Lso that the stacker'will operate smoothly and' without destructive strain@ ,Ai-further object is ,to provide a construction that can be V'adjusted either to operate as an ordinary overshot hay stacker without y automaticv extension and retraction of thefstack'er head occurring, or to cause automatic'extensioii and retrac-4 tion ofthe stacker .head'to occur. Iaccoinplish these objects as illustrated in the drawings and as hereinafter described; What I regard asznew will be set f fortlik inthe claims.

In the drawings Y Figiiie'l is a plan'view;

Fig. 2 is a side elevation, theirelative'pos'r' tiii ofthe .parts-as thelifting action begins being shown-in, full lines, the 'dotted -lines 'showing the relative Vposition off the parts when the stackerlhead' is partially raised ;vr

mechanismv for automatically moving the'` frame as the latter is raised or'plowered, and hoisting mechanism consisting of a system of levers, pulleys, and hoisting rope arv eXtensible frame relatively to thelifting 1 The novel feature of myy improved stacker will4 bel pointed out lin connection with the following detailed description of the 'em-f Y j bodim'ent thereof illustrated in the drawings; l The stacker'basefis formed offparallel" spaced sillsv -11, 'connected by a front cross :sill 12, yarear'1cross sill '13,'and an lin`-` termediatecross sill 14j Outwardlydive'rging braces 15 'extend from the center of therearV cross sill to the sills 10-11. Mounted upon the outer ends of the diverging'braces, l

arebraokets 16417 which have outwardlyy extending Vpins' 1 6a'17&*that form VpivotsA upon `which the `swinging lifting .framev is mounted; The lifting frame is composedf of side members or arms y1'8-'-19,l the-forward* Y ends ofv which are connectedjby a" cross bar 20, thel arinsfand cross .bar beingbraced l,by ktriangular plates 2li-422. ,Rockingly and`A` slidably 'supported' upon the 4lifting v frani'ex* by means which willfbe hereinafter desribd; isrthe extensible frame which com pivotally mounted on the stacker teeth and connected together with the transverse bar 29. The pitcher teeth are adjusted relatively to the stacker teeth by means of the strap and hook means 30. 31-32 indicate braces that diverge outwardly from the arms 213-34 of the extensible frame and aid in supporting the end portions of the stacker head.

The lifting frame is hoisted by means of the usual mechanism consisting of an A frame composed of bars 82% 34 pivotally supported upon the base and having pivotally mounted in its apex a lever 35, the forward end of the lever being connected with the triangular shaped plates 21-22 of the lifting frame by diverging rods 3G--37, the rearward end of the lever being connected with the rear sill 13 by a block and tackle means 38. A spreader 39 secured between the bars 33-84 prevents the A frame from buckling. Vhen the stacker head is in load receiving position, the hoisting mechanism is held in proper' operative position by a chain 40 extending between the forward end of the lever 35 and the diverging braces 15. When the stacker head is elevated, this chain of course is'slack, as indicated in Fig. 3. The lifting frame is prevented from passing too far beyond the perpendicular at the delivery point by stop ropes 41 42 secured at their upper ends to the lifting frame and after passing over blocks 41a42a are connected to sleeves 41h-42b slida'bly mounted on tubular bars 45-46, and arranged to bear against cushioning springs 43-44 mounted on the bars 45`46 Ias shown in Fig. 1. The bars 45-46 are secured to the front cross sill 12, the intermediate sill 14, and the parallel sills 10-11, and form,` pivot 'bearings for the A frame as well as supports for the sliding sleeves and cushioning springs.

When the lifting frame is hoisted, the extensible frame and the stacker head are automatically moved relatively to the lifting frame both angularly and longitudinally by mechanism now to be described.

Secured to each lifting frame arm-18419 is a bearing block 47, as best shown in Fig. 4. Pivotally supported upon each bearing block and spaced apart a distance sufficient to provide ample clearance Yfor the arms 23-24 of the eXtensible frame to move therebetween, is an outside bracket 48 and -an inside bracket 49. The pivot which supports said brackets is indicated by 47a in Figs. 2 and 4. The bracket 48 is provided` with a forward arm 50 and a rearward arm 52, and the bracket ,49 is providedwith a forward arm 51 and a rearwardarm53. The arms 50-52 and the.r arms 51-53thus form parallel bell crank levers spaced apart to admit of the passage therebetween of the arms 23-24 of the extensible frame. As indicated at a in Fig. 1 the end of each arm 50-51 is beveled or rounded to provide an inclined surface so as to prevent the arms 23-24 of the extensible frame from locking with the arms 50-51. The ends of the arms 50-52 are connected by a truss or stiffener brace 54, which is reinforced and armored with a meta-l strip 55 riveted thereto, and the ends of the arms 51-53 are likewise connected by a similar truss or stiifener brace. The forward arm 50 of each outside bell crank lever' is connected with the sill 10 by a strap 59, and the forward end of each inside bell crank is connected with the sill by a strap 59a, as shown in Fig. 1, said straps being spaced apart so that the lifting frame arms and the arms of the extensible frame can operate between them. The strap 59 is reinforced by a wooden bar 56, and the opposite side of said bar is connected with the arm 50 by a strap 58, as shown in Fig. 3. In like manner the strap 59n is reinforced bya wooden bar 57 and the side of .said bar is connected with the arm 51 by a strap 58a.

The medium of connection for the straps 59 and 59a and their reinforced bars 5(3 57 to the sill consists of an outstanding bracket 60 secured to the side of the sill and having a spreader 61, as best shown in Figs. 3 and 5, the straps and bars being pivotally secured to the bracket and spreader by a bolt 61a.

The rear arms 52-53 of each bell crank lever are pivotally connected with the arms 23-24 of the extensible frame by pivots 62, as shown in Figs. 2 and 3, and are p-rovided with a series of alined holes that register with a series of holes in the arms 23-24 for receiving said pivot and adjust ing the point at which said members are connected to each other, as the extent to which the stacker head is extended and retracted during the raising or lowering of the lifting frame depends upon the holes that are used for pivoting the bell crank levers and the extensible frame arms 23-24 together. The pivot 62 is illustrated in the drawings as being in the set of holes farthest from the pivot 47a of the bell crank levers and therefore the stacker is set to project the head to the greatest extent. If it be desired to operate the stacker without any extension or retraction of the head, as for instance, when building the base and lower portion of the stack, the pivots 62 of the bell crank levers are removed and inserted in the vertically positioned holes 63-68a through the arms 28424 and 18-19, shown in dotted lines in Fig. 2. Nhen thus secured together, the lifting and eXtensible frames operate as an ordi-nary overshot hay stacker. The bell crank levers at such time operatively connected with said extensible frame, means operated lby the swinging of said lifting frame for actuating said lever to move said extensible frame relatively to the lifting frame, and means whereby said extensible frame may be fixedly secured to said lifting frame and said lever rendered inoperative.
